SALT LAKE CITY - George Osmond, father of Donny and Marie Osmond and patriarch to the family's singing group, The Osmond Brothers, died Tuesday. He was 90.

George Osmond married his wife, Olive, on Dec. 1, 1944. She died in 2004. The couple were the parents of nine children, many of whom became singing stars. Alan, Wayne, Merrill and Jay Osmond first became famous as The Osmond Brothers, a barbershop quartet singing at Disneyland and on "The Andy Williams Show."
